To @ZZ wtom it' may concern:

Be it known that we, Janus BLACK and ORSON Bnncnnn, both of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Hydraulic Steam-Pump for Raising TVatcr, 3 and we hereby declare that the same is described and represented in the following specification and drawings.

rlhe nature of our improvement consists in connecting the top of the condenser with the valve-box, betweenthe induction and cduetion valves, by a pipewith a checlcvalve so arranged as to draw the air, &c. ,from the condenser when the water is drawn down in said pipe by the diaphragm when the vessel is filled with water, and to drive the air out of said pipe through another eheclcvalve into the discharge-pipe or elsewhere by the water when it is forced up in said pipe as it is expelled :from the vessel by the steam above the diaphragm, and thus draw the air from the condenser' by a column of water working the equivalent of an air-pump; second, in the arrangement ol a pipe with a valve in it leading from the bottom of the condenser to the chamber of the pump, so constructed and arranged as to draw the water from the condenser into the chamber of the pump by the action ofthe diaphragm or its equivalent, thus causing the waterpump to work an exhaust-pump or its equivalent to the condenser at thc same lime that it does its ordinary work.

To enable others skilled in the art to make and use our hydraulic steam-pump, we will proceed to describe its construction and operation, referring to the drawings above mentioned, in which the same letters indicate like parts in each ofthe figures.

Figure l represents the front; Fig. 2, a sec tion to the right ol" the line A* B of Fig. l; Fig. 3, the openings in the valve-seats, Figs. fl; and 5, the rotating valve.

XVe construct our pump in the form represented in the drawings,with two globular vessels, A A, each of which is made of two hemispherical cups with openings in the center and 'flanges at the edges, as represented, to facilitate fastening the two cups together, and at the same time to fasten the flexible diaphragm A, made of vulcanized india-rubber,

`and shown in Fig. 1, where the vessel A and diaphragm A2 are shown in section cut perpendicularly through the center, the cups on the inside being turned off with a gentle curve where they join the flanges at a a, so as to save the diaphragm from the unnecessary wear to which it would be exposed if the con nection of the iiange and cup were made with a square corner. The under cup of each vessel is connected to a valve-box, (see A3 A5,) which boxes have valves in them, so as to receive the water from the branched pipe B, which conducts the water to the pump from the source which supplies it. lThe water p asses fro m the pump or vessels through the same aperture that it entered, and from the valvebox A5 into the valve-box P', and thence into the branched pipe B2, which conducts it into the discharge-pipe Bi", which conveys it to the required destination. Thc frame C is fastened to the upper half of each ofthe vessels, as represented, lwhich frame supports the axis a' of the segment-lever C, the teeth upon the segments making into the racks C2 and C3 upon the traverse-rods CL and G5, which rods are supported by the frictiourollers a2 a? in the frame C. The traverse-rods pass down through the stuffing-boxes a a into the vessels A A', and are provided with a broad head or washer, a", and a movable washer, a, which is forced down by the nut I), so as to secure the center of the diaphragm A2, as represented in the vessel A, Fig. 1. The stop-cocks b if are opened when necessary to discharge the water which may accumulate above the d iaphragms from the condensation of the steam. The steanrpipe D is supported by the bar D', fastened to the flanges ol the vessels A AC A pipe from a steam-boiler is connected to the lower end of D, which conducts the steam into the valve-box D'l through the opening bf in the valve-seat and b* in thevalve D", andit passes from thence through the openings c c'iinto the pipes c c* to the pipes cL to the top of thc diaphragms in the vessels A A. to force thc diaphragms down. The valve D, turned by the shaft c', allows the steam from the Valvebox D2 to enter one vessel and force down the diaphragm, while it (the valve D2) allows the steam to escape from the other vessel through the same pipes that conducted in, and to pass out into one of cavities c2 c in the valve D, and from thence through the openings c* ci into the exhaust-pipe DVl and D, and it passes through the pipe D5 into the condenser E, which surrounds the discharge-pipe B. rlhe pipe E conducts the water from the dischargepipe into the condenser E,where the pipe surrounds the discharge-pipe, as represented by dotted lines, a-nd the water escapes through the perforations c c to condense the steam, after which it passes or is drawn from the condenser through the pipe D5 and cheek-valve d to the valve-box A pipe may be attached to the lower end of Di to supply the forcepump which feeds the boiler with hot water, which force-pump, we contemplate, may be worked by a lever fastened to the shaft a. The pipe E is provided with a cock, d', to regulate or stop the water from, flowing into the condenser. The valve E'l upon the pipe D is designed to let such a-portion or all the steam escape that is not intended to be condensed, in which case the cheek-valve (l might be fastened down and the cock al turned so as to supply sufficient water to feed the boiler, or it may be supplied from solne other source. The air and uncondensed steam is drawn from the condenserEthrough the valve d2 by the descent of the water in the pipe E when the diaphragm A2 is raised, and when it descends the Water is forced up in the pipe E and drives the air through the valve d" and pipe el" into the discharge-pipe B, as the valve d* prevents it from entering the condenser again. A portion of the pipe d andthe valve d are shown in section, (enlarged in Fig. G.) The valve-shaft c turns in the stuffing-boxes F F, fitted to the projections upon t-he valves box D2, and is operated in part by the lever F2, fastened to it and connected by the rod F:i

to the lever F* upon the shaft af, which is4 moved by the segments acted upon by the racks C2 C. rlhe sector G is fastened to the shaft d, which is .moved by the lever F2, as above mentioned, until the sector G carries the lever G2 and ball G so far past a perpendicular from the center of the shaft e that the ball GH falls and carries the sector and shaft e', moving the valve D, so that the cavity c covers the openings c and e", and permits the steam to pass from the pipe c into D, and at the same time allows the steam to pass from D through b3 and 6* into ci, the cavity ci covering c5, the slotfin the rod F3 permitting the lever F2 to be moved by the falling of the ball G3 above mentioned.

The hydraulic steam pump having been constructed and completed as above described, and a suction and discharge pipe properly attached thereto, or if the pump is placed so low that the water will flow into it a supply instead of a suction pipe may be attached to the branch pipe B, also a supplypipe froln a steanrboilcr connected to the pipe D, and a supply of steam let into the valve-box D2, passing therefrom through the pipe c in to the ves- 'sel A, forcing down the diaphragm Al and rod C", driving the water from A into the valvebox below, -and thence opening a valve similar to l-I, (represented invdotted lines in BQ) it flows through the branched pipe B2 and discharge-pipe B3 to its destination. When the diaphragm A2 and rod CL descend, they work the lever C, and draw up the rod C5 and diaphragm connected to it, drawing the water into A through the valve H. At the same time the air or steam above the diaphragm in A passes through the pipe c, valve-box D2, and pipes D", D, and D5 into the condenser E. As the lever O is vibrated, as above mentioned, it carries up the level` F, rod F", lever F, turning the valve D, so as to shut the steam from the pipe C, and at the same time it moves the sector G, so as to carry the lever Gfz and ball Gg so far past the perpendicular from the center c that the ball falls on the opposite side, carrying the sector with it and moving the valve D, so as to let the stealn into the vessel A', and force the diaphragm and rod Cidown, driving the water ont of A through the Valve H and pipes B2 and B to its destination. Then the rod C5 is carried down, it works the lever C and draws up the rod CL and dia phragm A2, forcing the steam from Athrough c', D, D, and D5 into the condenser E, the valve D being turned bythe ball G when it falls, so as to allow it to escape, and at the same time shuts the steam from the pipe c3 and places the valve so as to let the steam into A and allows it to escape from A', as heretofore described. lf it is desirable to work the pump and condense only a part of the steam, the balance may escape through the valve FF; or by removing the Valve the pump may be worked without condensing at all, when it will be necessary to supply the feed-pipe fol the boiler from some other source than the pipe Vhen the diaphragm A2 is forced down, it raises the water in the pipe E3 and drives the air from the pipe through the valve di, and when the diaphragm is raised it draws the water out of said pipe, and the air, 85e., from the condenser, through the valve d2, and when the diaphragm is forced down again the air, Src., is driven through the valve d, as before mentioned, and may be made to enter the discharge-pipe through zl, or otherwise. Thus the diaphragm causes the column of water to work the equivalent of an air-pump to the condenser. XVhen the diaphragm in the vessel A is raised, it draws the Water from the condenser through the pipe D5 and valve d, thus causing the diaphragm to work an exhaustpump to the condenser.

NV e contemplatel that the diaphragms may be made of such other materials besides that above mentioned as will answer the purpose, and fixing a fulerum for the lever Gl below the valve-shaft, so as to relieve the valve from the jar of the ball Gr3 when it falls.

XVe are confident that a pump can be constructed, as above described, to raise a given quantity of water in a stated time for onefourth of the cost of a common piston-'pump and steam-engine to operate the same, and that our pump will raise a given quantity of water to a stated height with half the steam or power required to operate a piston-pump and steam-engine to raise the same quantity of water to the same stated height. Consequently We should save fifty per eent. in the cost of boilers and fuel required and seventyiive per cent. of the oost of an engine and piston-pump to do the same amount of Work.

Vhat we claim as our invention, and desire to secure by Letters Patent, is-

1. The pipe E and 'Valves d2 and d, or their equivalents, so Constructed and arranged as to draw the air, 85e., from the condenser and drive it into the discharge-pipe or elsewhere by the column, of Water in said pipe, operated by the Working ofthe diaphragm, which causes said column of Water to Work the equivalent of an air-pump to the condenser.

In testimony whereof we have hereunto signed our naines before two subscribing Wit messes.
